To all whom it lmay concern.'

Be it known that l, .EmioND RosENBuRG, a citizen of the VFrench cpul'ilic', residing at Paris, France', have invented certain new and useful Improvements in (Table-Reels, ot which the following is a specification.

My invention relates to cable reels and particularly to that form of reel used on mining locomotives. These reels serve, to wind up 'and pay 'out a flexible conductor which may be attached'at one end to a smirce oi' current, such as a trolley wire7 and which supplies current to the locomotive when it "gather-- ing cars from the working faces oi' 'the rooms of ini-nes. By usinga ilexiblc cable and a reel in this way, the necessity of having trol- An object of my invention is to provide a new and improved construction ot reel and a simple means for driving the same and keeping the 'flexible conductor under a constant tension.

My invention will be more .fully understood form of apparatus in which my invention :may be embodied.

Referring` to the drawing, in which. like parts are denoted throughout the sev ral views bythe same reference characters, vFigure 1 is a more or less diagrammatiiz sidc elevation of a locomotive equipped with my invention; Fig. 2 is a plan view thereof; and Fig. 3 is a :sectional elevation through the reel shown in Figs. l and if?.

The frame of a mining locomotive is shown at 5. This may be driven by motors geared t0 the axles and controlled through asuitable controller (not shown) in the usual manner.- As is usual in locomotivesv ol this kind, the cable reel is 'mounted on the top thereof and a flexible conductor t5 passes through a guide 7 and is attached at one end to a source ot' current supply, such as the trolley wire 8. Y

In the form oi reel shown a supporting frame lOis secured to the top of the locomotive. This frame carries a rotatable driving member 11 on the bottom of whlch 1s an annular rack 12 which engaged by a `pinion 13 on a 'shaft- 14 mounted 'in a bearing in the y 3. The shat il one of the axles of the locomotive. A winding drum 17 which may be ol any suitable construction, as for instance strips of sheet metal suitably bent and fastened together, is supported on a llange 18 which is a part of 60 the driving member 1 1. A suitable washer 1.01 may be interposed between the 'flange 18 and the frame 2t) of, the drum 17. A positive but yielding driving connection is inter iosed between the driving member 11 and the 65 winding drum 1T. This consists of a spiral spring 21 'secured at its inner end 22 to the hub of the driving` member 11 and at its outer ond 33S to the inside oll 'the drum 17.

The flexible conductor (i. which serves to convey current to the motors of the locomotive, is brought through an opening in the drum 17 and is secured at its inner end to a binding post .25 insulated from the frame of the reel. This binding post is connected by a spring or linger 26 with a suitable contactl plate 2.7. The under side of this contact plate 27 is held against the end of a contact member 2S which is secured to the conductor 2) carrying'current to thc motors. num- 80 ber oll other springs 26 may be attached to the Contact plate a nd serve to hold it lirmly against the .contact member The conhurt'member and the springs 26 and 2o arc insulated from the l'rame. of' the roel as 85 shown.

ri`hc operation ol my imprinted reel is obvious. 'lhe spiral spring 21 is originally placed under tension and this tension is constantly exerted ou the ilexible conductor (i, thereby keeping said conductor morel or less taut. As the locomotive moves back and forth the rcel is rot-ated in one direction or the other by means oi' the driving connection between the reel and axle. 'lho sprocket 95 wheels and gearing are, ol course, so proportioned that the reel winds and unwinds at the same rate as the locomotive moves. The reel therefore takes up and pays out the proper amount ol conductor and the tension 100 exerted by the spiral spring remains unchanged. "lhe cable is thus` properly taken caro of.

\Vhile l. have shown one particular lorm of y my invention, l wish it understood that l realize that this ,:onstruction may be varied to a considerable extent without departing from the spirit olA my invention. it is my ineinion to rover ali such modifications in 1What i claim as new and desire to secure by Letters Patent of the United. States,-is

l. in combination, a vehicle arranged for iorvvard and reversetmovement, a cable reel earried thereby, a flexible cable having one' end connected to said reel andthe o'tlier'se-` eared at a 'lixed point, anda positive `but yielding driving connection between' f said' reel and a part which rotates with thefmovenient of the vehicle'. v l l y l 2. ln combination, a movable'vehiole, ya cable reel carried thereby, a flexible cable having one end connected to said reel and the other secured at a iixed point, and-a spring driving connection between said reeljand-a part which rotates With the movement of the vehicle.
